Comment on How do you get started working in car audio? by seanspin

Ben, Try making friends at a car audio shop. Typically, if you show interest and ask a lot of questions; many shops let people hang out in and around the installation bays. This especiallyworks if you are young and the owners are young or hip. You may want to trade some sweeping and cleaning time to learn. Shops are always having to be swept and cleaned; its a dirty job sometimes…. Good luck!

your 5th gear is overdrive on a manual tranny.

normally, a transmission, auto or manual is designed that the highest gear causes the output shaft to rotate at the same speed as the engine. If if the output shaft rotates FASTER than the input speed (@the clutch or torque converter), the transmission is designed with overdrive gearing , usually the hightest gear of an auto box and sometimes the top two gears of a manual transmission. In the past, an OVERDRIVE unit was a two speed attachment to the output shaft of the transmission that was engaged by an electic clutch after it was in the highest gear to decrease engine RPM for higher cruising speed and better gas milage. The o’drive on my ‘64 TR4 would drop engine RPM by about 1000RPM when engaged. In modern cars, the overdrive gearing is usually built into the gear box for simplicity of design.

It is simply one more and sometimes two more gear ratios. For example the manual transmissions in the Corvette and Viper have two over drives that provide up to 50% over drive verses 30% on most automatics.

Easy – exactly the same way automatic trans does. There are 5 and even 6 spd automatic and manual transmissions, and when in 4 th (direct or straight) gear, engine crankshaft turns with the same speed as the trans output shaft while in OD gear the engine rotates slower than the output shaft. The only difference is that in automatic trans it shifts automatically, and in manual – manually.

The only difference is that on a stick shift you choose when to shift gears. You can still have the same gears.

The highest gear you manually shift into is the overdrive.

yes it can……..

quite often cars have an electric overdrive… push the button & the revs drop 500 to a 1000 revs..
I should point out that overdrive was an option on many manual transmission cars of the past. In my own vehicle’s case, there was an electric overdrive option available from the factory – it trades torque for engine speed, just as if it was a higher gear. The difference (in my car’s case, at least) is that the overdrive is a separate unit from the transmission. It is activated using a dashboard control. As a separate component, it can be in effect over multiple gears (from 2 to 4, in my case).
